PHR 803t driven with the lava flex drive. When I turn it on there is about 0.25 seconds before the laser starts to lase. Is this normal or a bad sign?

Re:  Done! (Modyfied Dorcy jr)..DONE!!!!!! Very nice! What mw did you go with?

I too built my first laser yesterday. It worked great for a bit, then while I was playing around with it I went to turn it on and...nothing. I had an LED. I was using a PHR-803T, DarkHorse heat sink, and a Dr. Lava drive. I ordered the Dr. Lava preset to 110ma. I remade the laser this morning...

Not the controls unless you could burn through the airplanes skin (as far as I know only the US government has a laser with that capability). Navigation: No. Same as the controls. Unless you were trying to land with an MLS (Microwave Landing System) and someone got you with a MASER. MLS is rare...

(i had...

what country? in america your vision only has to be correctable to 20/20.

ok i'll try: a direct hit to the eyes, and/or cockpit illumination would be distracting, but the degree of distraction would depend on the intensity of the laser light which would be affected by the power of the laser and distance from the source. you wouldn't necessarily need cockpit glare to...

thats what i was worried about. i was able to repair some delicate stuff inside of a wireless transmitter with one, but i dont want to fry a good diode. Thanks!

double post.

So are the 'cold heat' type of soldering irons safe for our applications or do i need to get a regular iron?

if you filtered out the green light the runway threshold lights and the taxiway lead off lights would be filtered out as well. you wouldnt be able to tell where the runway began or where to start turning to get off the runway. you might end up in the dirt. it would still be doable but the visual...
